Added osg::Image::setPixelFormat(..) and setInternalTextureFormat(), and

renamed osg::Image::pixelFormat(), internalTextureFormat(),dataType() to
osg::Image::getPixelFormat() etc.  These changes are to bring it more
into line with the style of the rest of the OSG.

Updated the rest of the distribution to take account for these names changes.
